Answer:
The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:
and not 
Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.
I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.
Solving the equation
Using distribution
Add 
both sides
Add 12 both sides
Divide both sides by 5
Eli traveled a total of 8.6 miles. He went to the library and back. 3.75 + 3.75. and he also added and extra 1 1/10 mile. so, 3.75 x 2 = 7.5, 7.5 + 1 1/10 = 8.6. Hope that helped!
The perpendicular line to x-6y=2, and passing through (2, 4) is y=-6x+16
3x - 10 = x + 4 <== ur equation
three times a number.....3x...with the x representing the number
ten less....3x - 10
is the same as...means =
that number (x) increased by 4....x + 4
so we have 3x - 10 = x + 4...
3x - 10 = x + 4
3x - x = 4 + 10
2x = 14
x = 14/2
x = 7....and that number is 7
Answer:
Step-by-step explanation:
x + 29 + 12 = 89
x + 41 = 89
x = 48 for <CED
